Following it’s interactive wall in South Korea last year, UK supermarket Tesco has set the bar high in online grocery innovation with a new interactive virtual shopping wall at Gatwick Airport.

The grocer has kicked off a two-week trial of 10 interactive shopping screens designed to target holidaymakers yesterday.

Shoppers in the London airport’s North Terminal departure lounge can scan posters of Tesco’s 80 most popular items to fill a shopping basket using an app.

The app also allows customers to browse 20,000 extra products and to have the items delivered or collected up to three weeks after ordering.

Tesco said that the average traveller at Gatwick spends 70 minutes in the departure lounge and is offering staple goods that shoppers will be keen to have in the fridge when they return home from holiday.

Tesco estimates that 90% of the UK population will have a smartphone by 2016 and that it will double its online grocery sales to £5.5bn in the next five years.
